DNS server removes his own record

[Guest]

Please help,

We have a problem. We have more than one DNS server. One DNS server removes
his own record from the reverse lookup zone. So we register the record again
(manualy or with ipconfig /registerdns) and then the record replicates to all
the DNS servers. But in one our the record is deleted.
So when we disable the DNS services on that server and we add the record,
the record doesnt remove.
So the server is an Windows Server 2003. Its the first DC (with all the
forest and domain roles), DHCP server and (when it works) DNS server.
His own ip settings for DNS are empty (127.0.0.1).

What are the scavenging, TTL and all those kinds of settings for the domain?
Is it AD integrated?

Since the record is created with ipconfig /registerdns I can rule out PTR
registration being disabled. But just to be sure add this to the registry
and set the value to 0 (Register PTR).
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters\DisableReverseAddressRegistrations


Data type: REG_DWORD
Range: 0 - 1
Default value: 0


It is not recommended to use 127.0.0.1 as the DNS address because it is know
to cause registration problems, you should use the actual private IP of the
private interface.
Also the you have DNS listening on that address on the interfaces tab or the
DNS server's property sheet.
